Abstract (en)

[origin: WO2021002797A1] The present disclosure pertains to method of forming a paperboard packaging container (1) from a rectangular body blank (2), the method comprising the following steps: a) providing a rectangular body blank (2), the body blank (2) having a longitudinal direction (L) and a transverse direction (T), the body blank (2) having a first transverse edge (3) and a second transverse edge (4) and a first and a second side edge (5,6), the body blank (2) being made from a laminate sheet material comprising a carton substrate layer, the body blank comprising two or more parallel crease lines (9), the parallel crease lines (9) each being arranged with a distance (d2) of from 2 mm to 15 mm from the second side edge (6); b) forming a tubular container body (12) from the rectangular body blank (2), the container body having a first body opening (14) and a second body opening (16); c) sealing together the first and the second side edge (5,6) in a but-to-but seal using a sealing strip (22) having a sealing strip width (ws), the sealing strip (22) extending over a non-creased area (23) bridging the first and the second side edge (5,6); d) presenting the tubular container body (12) to a crease line forming station (24) and providing the non-creased area (23) bridging over the sealing strip (22) with two or more bridging crease lines (21) such that a bridging crease line area (25) is formed; e) closing the second body opening (16) by pressing a paperboard disc (26) into the second body opening (16); f) forming a curled second edge (28) by folding or rolling the second end (15) of the container body wall (17) inwardly; g) filling the packaging container (1) with bulk solids; h) closing the upper body opening (14); i) wherein steps h) and subsequently step g) could alternatively come after step d). The present disclosure also relates to a paperboard packaging container.
